Re: CollapseFilter with the latest Solr in trunk

I have not looked at this in a while, but I think the biggest thing it is missing right now is a champion -- someone to get the patches (and bug fixes) to a state where it can easily be committed. "Minor bug fixes" are road blocks to getting things integrated.

Once somebody really makes it work, I'm sure it will be released!

I wish it would be planned for 1.4 :))

Thanks for sharing!
It would be good if you (of Jeff from Zappos or anyone
making changes to this) could put up a new patch for this
most-voted-JIRA-issue.

Ok, here is how I fixed this problem:

 public DocListAndSet

getDocListAndSet(Query query, ListfilterList,

DocSet docSet, Sort lsort, int offset, int len, int

flags) throwsIOException {


   //DocListAndSet ret = new

DocListAndSet();




  //getDocListC(ret,query,filterList,docSet,lsort,offset,len,
flags |=

GET_DOCSET);

DocSet theFilt = getDocSet(filterList);

if (docSet != null) theFilt = (theFilt != null) ?
theFilt.intersection(docSet) : docSet;

   QueryCommand qc = new

QueryCommand();




  qc.setQuery(query).setFilter(theFilt);




  qc.setSort(lsort).setOffset(offset).setLen(len).setFlags(flags
|=

GET_DOCSET);

   QueryResult result = new

QueryResult();


   getDocListC(result,qc);



   return

result.getDocListAndSet();


 }


There is also one-off error in CollapseFilter which

you can find solution on

Jira.

Cheers,
Cuong

We are currently trying to do the same

can use fq as long as collapsing is turned

on.  If we just send a normal

document level query with an fq parameter it

blows up.


Additionally, it does not appear that the

collapse.facet option works at

all.

Subject: CollapseFilter with the latest Solr

in trunk


Hi all,

Have any one try to use CollapseFilter with

the latest version of Solr in

trunk? However, it looks like Solr 1.4

doesn't allow calling

setFilterList()

and setFilter() on one instance of the

QueryCommand. I modified the code

in

QueryCommand to allow this:

   public QueryCommand

setFilterList(Query f) {

//      if( filter != null )

{

//        throw new

IllegalArgumentException( "Either filter or

filterList

may be set in the QueryCommand, but not

both." );

//      }
     filterList =

null;

     if (f !=

null) {



  filterList = new ArrayList(2);



  filterList.add(f);

     }
     return this;
   }

However, I still have a problem which

prevent query filters from working

when used in conjunction with

CollapseFilter. In other words, query

filters

doesn't seem to have any effects on the

result set when CollapseFilter is

used.

The other problem is related to OpenBitSet:

java.lang.ArrayIndexOutOfBoundsException:

I think CollapseFilter is rather an

important function in Solr that gets

used quite frequently. Does anyone have a

solution for this?
